Answer:
B. x=75
Step-by-step explanation:
First, write out the equation as you have it:
x/5=15
Then, multiply both sides of the equation by 5/1:
5/1(x/5)=15(5/1)
Your result is:
x=75
If you want an expression it would be 9-5x
Answer: The graph is attached.
Step-by-step explanation:
By definition, the line intersects the y-axis when
.
Then, in order to find the y-intercept, substitute
into the equation and solve for "y":

By definition, the line intersects the x-axis when
.
Then, in order to find the x-intercept, you can substitute
into the equation and then you must solve for "x". Then you get:

Knowing that the line passes through the points
and
, you can graph it (The graph is attached).
